ReplaceAll Google script

I've got a problem, I am trying to use a replace function in JavaScript and I cannot get it to work. I'm using:

var pagename = projectname.replace (" ", "");

But it only takes the first space, I wanted to take all the spaces. example:

"My first project 1" = "Myfirstproject1", ie get everything together.

I'm developing the script of google apps.

Thank you.

Unfortunately, replaceAll is not available in Google AppScript. You may use RegExp version of replace to implement replaceAll. If you want to create some kind of generic solution, you need to escape subject from special RegExp characters, as symbols like .^ (and many others) have special meaning in regular expressions.

function strReplaceAll(subject, search, replacement) {
  function escapeRegExp(str) { return str.toString().replace(/[^A-Za-z0-9_]/g, '\\$&'); }
  search = search instanceof RegExp ? search : new RegExp(escapeRegExp(search), 'g');
  return subject.replace(search, replacement);
}

We may also add this to string class, but I suggest to test if is already here, just in case it may be added in later versions of Google AppScript.

if (String.prototype['replaceAll'] == null) { 
  String.prototype['replaceAll'] = function(search, replacement) { 
    return strReplaceAll(this, search, replacement) 
  }; 
}

Also, please pay attention, that $ has special meaning in replacement string in replaceAll (JavaScript also work this way). So probably you need additional function escapeReplacementString to handle this in case pure text-to-text replace (this function is also useful in JavaScript).

function escapeReplacementString(str) { return str.toString().replace(/\$/g, '$$$&'); }

So generic text-to-text replace will be like text.replaceAll(search, escapeReplacementString(replace)):

var text = 'Money is +'; search = '+'; replace = '$& and $$';
console.log(text.replaceAll(search, replace)); // gives you 'Money is + and $' [?!]
console.log(text.replaceAll(search, escapeReplacementString(replace))); // gives 'Money is $& and $$'

You use this code outside other function. 

String.prototype.replaceAll = function(search, replacement) {
        var target = this;
        return target.replace(new RegExp(search, 'g'), replacement);
};

Then you can use replaceAll function. Example : 

var text = "H e l l o W o r l d";    
text = text.replaceAll(" " , "");

Result : HelloWorld

You should try :

var pagename = projectname.replace (/\s/g, '');

the g at the end of the regular expression, is a flag indicating to the replace method that it shouldn't replace only the first occurrence of the space character.
